[i-g-t, v7, 0/2] tests/i915/pm_rc6_residency: Use sysfs to achieve peak frequency

[Sk Anirban]

Leverage IGT spinner to trigger frequency scaling and
set RPS minimum frequency to RP0 for achieving peak frequency.
This method replaces the existing waitboost mechanism used
to reach maximum frequency.

v4:
 - Cosmetic changes (Riana)

v5:
 - Limit the power consumption test to GT0 only

v6:
 - Fix frequency restoration (Riana)

v7:
 - Fix variable scope (Riana)
